PrintTicket(Stream)

使用符合 XML 列印結構描述的 XML 資料流 (包含 PrintTicket 文件),初始化 PrintTicket 類別的新執行個體。

public:
 PrintTicket(System::IO::Stream ^ xmlStream);
public PrintTicket (System.IO.Stream xmlStream);
new System.Printing.PrintTicket : System.IO.Stream -> System.Printing.PrintTicket
Public Sub New (xmlStream As Stream)

參數

xmlStream
Stream

描述列印工作並且符合列印結構描述的 XML 資料流。

例外狀況

xmlStreamnull

xmlStream 不是有效的 XML。

備註

建構函式不會將數據流的讀寫位置重設為其原始位置。 因此,您應該在呼叫建構函式之後立即重設它。

整個 PrintTicket 檔會儲存在 物件的非公用欄位中,包括其中 XML 元素,表示類別之任何公用屬性 PrintTicket 未表示的較不通用功能。 事實上,如果產生 PrintTicket 檔的驅動程式使用 列印架構的私人延伸模組,該私用定義的標記也會儲存為非公用 PrintTicket 檔的一部分。

如果有任何,則檔的私人部分不會由建構函式驗證,但會驗證所有 列印架構定義的元件,包括類別之任何公用屬性未表示的部分 PrintTicket 。 因此, FormatException 即使對應至公用屬性的所有 XML 標記都有效,也可能擲回 。

當的任何屬性 PrintTicket 寫入時,此非公用 PrintTicket 檔也會變更。

這是和 SaveTo 方法所GetXmlStream傳回的非公用 PrintTicket 檔。
